> there should be a way for someone to commit to some dish, started at some time, and then others can "hook" onto the order for a discount This is how Uber Eats already works in Toronto. There is a section in the app with restaurants that have orders already in progress and with a timer on each one and if you order within that limited time, the delivery fee is $0.
